[0002] An electricity meter is used to measure electrical energy. The meter consists of a housing and a cover plate. The cover plate is located above the wiring terminals on the housing. The cover plate, in conjunction with the housing, creates a sealed connection to the wiring terminals. Finally, a sealing structure secures the cover plate to the housing, preventing unauthorized disconnection or electricity theft.

[0003] Most existing electricity meter casing fixing structures use sealant or bolts to install the top cover and bottom plate of the electricity meter. However, after long-term use, the sealant may age and deteriorate, leading to cracks in the electricity meter casing or corrosion of the bolts, thus affecting the casing strength. Therefore, there is an urgent need for an electricity meter casing fixing structure to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a housing fixing structure for an electricity meter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a housing fixing structure for an electricity meter, including a base plate for assembling the electricity meter housing and a top cover for mounting components in the electricity meter, wherein multiple terminals are fixedly installed on one side of the base plate and an electricity meter control device is fixedly installed on the top surface of the top cover;

[0006] A U-shaped insert plate is fixedly installed at the bottom of the top cover, and a U-shaped slot is opened on the top surface of the bottom plate, and the diameter of the U-shaped insert plate matches the inner diameter of the U-shaped slot opened on the top surface of the bottom plate.

[0007] The bottom of the base plate has a U-shaped slot opened horizontally, and multiple mounting cylinders are fixedly installed on the opposite side walls of the base plate. The bottom of the mounting cylinder has a through hole that extends into the interior of the U-shaped slot.

[0008] An insert rod is slidably installed inside the mounting cylinder. A turntable is fixedly installed at one end of the insert rod extending to the outside of the mounting cylinder. Two elliptical plates are symmetrically fixedly installed at one end of the insert rod extending into the U-shaped slot. The two elliptical plates are separated. The side wall of the U-shaped insert plate and the elliptical plates are provided with multiple elliptical holes corresponding to the elliptical plates, and the elliptical holes match the elliptical plates.

[0009] Preferably, a sealing gasket is fixedly adhered to the outer wall of the U-shaped insert plate fixedly installed at the bottom of the upper cover.

[0010] Preferably, the outer wall of the sealing gasket is slidably fitted to the inner wall of the U-shaped groove opened on the top surface of the base plate.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] like Figures 1 to 4 The main structure of the housing fixing structure of an electricity meter shown is a base plate 1 for assembling the electricity meter housing and a top cover 3 for installing components in the electricity meter. Multiple terminals 2 are fixedly installed on one side of the base plate 1, and an electricity meter control device 4 is fixedly installed on the top surface of the top cover 3.

[0030] A U-shaped insert plate 7 is fixedly installed at the bottom of the top cover 3, and a U-shaped slot 8 is opened on the top surface of the bottom plate 1. The diameter of the U-shaped insert plate 7 matches the inner diameter of the U-shaped slot 8 opened on the top surface of the bottom plate 1. Thanks to the U-shaped insert plate 7 at the bottom of the top cover 3 and the U-shaped slot 8 on the top surface of the bottom plate 1, by sliding the U-shaped insert plate 7 into the inside of the U-shaped slot 8, a seal can be effectively formed between the top cover 3 and the bottom plate 1, thereby effectively improving the stability of the installation between the top cover 3 and the bottom plate 1.

[0031] A U-shaped slot 5 is horizontally provided at the bottom of the base plate 1. The U-shaped slot 5 is used to install the device.

[0032] Multiple mounting cylinders 6 are fixedly installed on opposite sidewalls of the base plate 1. Each mounting cylinder 6 has a through hole at its bottom extending into the interior of a U-shaped slot 8. A rod 9 is slidably installed inside the mounting cylinder 6. A turntable 10 is fixedly installed at one end of the rod 9 extending to the outside of the mounting cylinder 6. Two elliptical plates 11 are symmetrically fixedly installed at the other end of the rod 9 extending into the U-shaped slot 8, with the two elliptical plates 11 being spaced apart. Multiple elliptical holes 12 are correspondingly opened on the sidewall of the U-shaped insert 7 and the elliptical holes 12 match the elliptical plates 11. This design benefits from the mounting cylinder 6, the rod 9, and the two elliptical plates 10. The 1 and the oval hole 12 are designed so that after the U-shaped insert plate 7 is inserted into the U-shaped slot 8, the insert rod 9 is pushed to slide into the U-shaped slot 8. At the same time, the two oval plates 11 fixed at the end of the insert plate 9 extend into the oval hole 12 opened on the side wall of the U-shaped insert plate 7. When one of the two oval plates 11 passes through the oval hole 12, the two oval plates 11 will be located on both sides of the U-shaped insert plate 7. At this time, the insert rod 9 is rotated to rotate the two oval plates 11 to a vertical position, so that the U-shaped insert plate 7 can be limited and locked, thereby further limiting the upper cover 3.

[0033] A sealing gasket 13 is fixedly bonded to the outer wall of the U-shaped insert plate 7 fixedly installed at the bottom of the top cover 3. The outer wall of the sealing gasket 13 is slidably and sealingly attached to the inner wall of the U-shaped slot 8 opened on the top surface of the bottom plate 1. The outer wall of the sealing gasket 13 fixedly bonded to the outer wall of the U-shaped insert plate 7 will slidably and sealingly attach to the inner wall of the U-shaped slot 8, thereby further improving the sealing effect between the U-shaped insert plate 7 and the U-shaped slot 8.

[0034] A rectangular sealing ring 14 is fixedly bonded to the top surface of the base plate 1, and the top surface of the rectangular sealing ring 14 is sealed and fitted to the bottom of the top cover 3. Thanks to the setting of the rectangular sealing ring 14, the sealing effect between the base plate 1 and the top cover 3 can be effectively improved.

[0035] A push spring 15 is fixedly installed on the side of the turntable 10 near the elliptical card plate 11. A sliding ring 16 is fixedly installed at the end of the push spring 15. The side wall of the sliding ring 16 slides against the side wall of the base plate 1. The push spring 15 can further improve the limiting effect of the elliptical card plate 11 on the U-shaped insert plate 7.

[0036] The turntable 10 has a cross groove 17 on the side away from the plug 9. Thanks to the cross groove 17, it can be pressed and rotated with the help of tools such as screwdrivers.

[0037] Working principle

[0038] In use, the casing fixing structure of this energy meter is as follows: First, the upper cover 3 is installed onto the base plate 1. At the same time, the U-shaped insert 7 fixedly installed at the bottom of the upper cover 3 is inserted into the U-shaped slot 8 opened on the top surface of the base plate 1. At this time, the elliptical hole 12 opened on the U-shaped insert 7 will be aligned with the elliptical card 11. Then, the turntable 10 extending to the outside of the mounting cylinder 6 is pushed to move the insert rod 9 and the elliptical card 11 fixedly installed at the end of the insert rod 9 into the elliptical hole 12. At this time, the elliptical card 11 is set in two symmetrically separated positions. Therefore, when one of the elliptical card 11 passes through the elliptical hole 12, the turntable 10 is rotated to make the two elliptical card 11 and the elliptical hole 12 misaligned. This can effectively limit the position of the U-shaped insert 7. At the same time, under the action of the push spring 15, the fixing effect of the elliptical card 11 on the U-shaped insert 7 will be further improved.
